Development of functional composite materials by addition of inorganic inclusions to polymer matrix attracts growing attention in last decades and carbon nanotubes (CNT) attract particular interest as reinforcement material due to their unique properties tunable by doping and functionalization. However such material characteristics depend not only on the concentration and properties of nanoinclusions but also o...
Apresentação efetuada no European Congress and Exhibition on Advanced Materials and Processes - EuroMat 2013, em Sevilha, Espanha, 2013 ; Development of functional composite materials by addition of inorganic inclusions to polymer matrix attracts growing attention in last decades. However such material characteristics depend not only on the concentration and properties of nanoinclusions but also on their distr...
Studies developed for the past years and recent earthquakes have brought to light the importance that efficient connections between structural elements can have in the global behaviour of the structure. Although out-of-plane mechanisms of masonry walls are considered to be local, the reality is that their occurrence can lead to total collapse of the structure. The scarcity of data, both at experimental and nume...
Poster "Advanced Hybrid Materials I I: design and applications" (Simposio P) ; Development of the hybrid materials with predefined properties by addition of inorganic nanoinclusions to a polymer material constitutes a hard challenge due to significant properties’ variations depending on inclusion’s distribution and interaction. To understand structure-property relations in such materials optical image analys...
Apresentação efectuada no E-MRS 2012 SPRING MEETING, Simpósio R "Science and technology of nanotubes, graphene and 2D layered materials", Strasbourg, France, 2012 ; Modification of carbon nanotubes by doping and functionalization is widely used to control individual nanotubes’ properties and interaction with surrounding media such as polymer matrix. As it is known from experiments and theoretical calculations...
Resumo ; The development of composites by addition of carbon nanotubes (CNT) to a polymer matrix is of particular interest due to significant changes in the composite properties depending on its morphology. To understand structure-property relations in such materials a computer code was developed to create a model composite structure with a non-uniform distribution probability of CTNs within the polymer matrix...
The global structural performance of masonry buildings, under earthquake loading, is affected by the efficiency of wall-to-floor connections, since they assure the continuity of the energy path and prevent the occurrence of most of the local collapse mechanisms. In fact, out-of-plane behaviour of masonry walls observed in recent seismic events showed the critical importance of proper connections in historical b...
The use of artificial implants provides a palliative or permanent solution for individuals who have lost some bodily function through disease, an accident or natural wear. This functional loss can be compensated for by the use of medical devices produced from special biomaterials. Titanium alloy (Ti-6Al-4V) is a well-established primary metallic biomaterial for orthopedic implants, but the toxicity of the chemi...
Os tumores ováricos secretores de androgénios são raros constituindo cerca de 1% de todas as neoplasias do ovário. Descreve-se o caso clínico de uma doente do sexo feminino, 67 anos de idade, que recorre à consulta por queixas de hirsutismo (score 23) e alopécia com padrão androgenético A avaliação laboratorial revelou níveis séricos elevados de testosterona. A ecografia ginecológica por via transvaginal permit...
